I am using custom payment module and upon receiving failed transaction response from my custom payment gateway I would like to
save the order with "pending_payment" state/status and not send any order email.
I do not want to create any invoice /process it or send any invoice email.
Also I would like to redirect my customers to a failure page or maybe checkout/cart page but with a message at the top saying their payment details was erroneous, and please try again.
Once I receive a 'Failed' response from my payment gateway I am able to save the order to pending_payment status and stopping it form sending a new order email but I'm not able to stop it from invoicing n hence stop d invoice email from being sent out.
I'm calling an Observer on sales_order_place_after event in my custom payment module which invoices the orders and sends the invoice email on successful transactions.
Now I dont know if that file needs editing too(app/code/local/Mage/Paymentmodule/Model/Observer.php) or just my app/code/local/Mage/Paymentmodule/Model/PaymentMethod.php is enough for this.
PaymentMethod.php
public function capture(Varien_Object $payment, $amount)
{
$error = false;
// check for payment
if($amount > 0)
{
$payment->setAmount($amount);
$order = $payment->getOrder();
if($payment->getTxnNumber() == "")
{
$transaction = $this->_build($payment, self::TRANSACTION_PREAUTH);
$authResponse = $this->_send($transaction);
if($authResponse->getResponseCode() > 0 && $authResponse->getResponseCode() <= self::ERROR_CODE_LIMIT)
{
$payment->setCcApproval($authResponse->getReceiptId())
->setLastTransId($authResponse->getReceiptId())
->setCcTransId($authResponse->getTxnNumber()) ->setCcCidStatus($this->getCvdDescription($authResponse->getCvdResultCode()));
}
else if($authResponse->getResponseCode() > self::ERROR_CODE_LIMIT && $authResponse->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT)
{
$order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
$order->setCanSendNewEmailFlag(false);
$order->setCanInvoiceFlag(false);
}
else
{
$order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
$order->setCanSendNewEmailFlag(false);
$order->setCanInvoiceFlag(false);
}
}
$check = $this->checkCvdResponse($authResponse->getCvdResultCode());
if($check == true)
{
$order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
$order->setCanSendNewEmailFlag(false);
$order->setCanInvoiceFlag(false);
}
else
{
$transaction_completion = $this->_build($payment, self::TRANSACTION_COMPLETION);
$response = $this->_send($transaction_completion);
if($response->getResponseCode() > 0 && $response->getResponseCode() <= self::ERROR_CODE_LIMIT)
{
$payment->setStatus(self::STATUS_SUCCESS);
$payment->setCcApproval($response->getReceiptId())
->setLastTransId($response->getReferenceNum())
->setCcTransId($response->getTxnNumber())
->setCcAvsStatus($this->getAvsDescription($authResponse->getAvsResultCode()))
->setCcCidStatus($this->getCvdDescription($authResponse->getCvdResultCode()));
}
else if($response->getResponseCode() > self::ERROR_CODE_LIMIT && $response->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT)
{
$order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false)->save();
$order->setCanSendNewEmailFlag(false);
$order->setCanInvoiceFlag(false);
}
else
{
$order->setState(Mage_Sales_Model_Order::STATE_PENDING_PAYMENT, 'pending_payment', '', false) ->save();
$order->setCanSendNewEmailFlag(false);
$order->setCanInvoiceFlag(false);
}
}
}
else
{
$error = Mage::helper('paygate')->__('Invalid amount for authorization.');
}
if ($error !== false)
Mage::throwException($error);
return $this;
}
Observer.php
public function implementOrderStatus($event)
{
$order = $event->getEvent()->getOrder();
if ($this->_getPaymentMethod($order) == 'custompaymentmodule')
{
if($order->getState() == 'pending_payment')
{
$order->setCanSendNewEmailFlag(false);
$order->setCanInvoiceFlag(false);
}
if ($order->canInvoice())
$this->_processOrderStatus($order);
}
return $this;
}
Any ideas how can I just save it pending_payment state and stop it form invoicing and redirect to cart page with an appropriate message.
Any help on solving any of the bits would be highly appreciated. Thanks
I found a partial solution to my problem. On failed payment transactions, instead of setting the pending_payment state in my PaymentMethod.php, I'm setting the Payment status to Declined and setting CcTransId to NULL
Then using this condition in my Observer.php I'm saving that order with pending_payment status.
Here's d modified code
PaymentMethod.php
if($payment->getTxnNumber() == "")
{
<!-- SOME CODE -->
if($authResponse->getResponseCode() > 0 && $authResponse->getResponseCode() <= self::ERROR_CODE_LIMIT)
{
<!-- SUCCESSFUL TRANSACTION CODE
}
else if($authResponse->getResponseCode() > self::ERROR_CODE_LIMIT && $authResponse->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT)
{
$payment->setStatus(self::STATUS_DECLINED);
}
else
{
$payment->setStatus(self::STATUS_DECLINED);
}
}
$check = $this->checkCvdResponse($authResponse->getCvdResultCode());
if($check == true)
{
$payment->setStatus(self::STATUS_DECLINED);
$payment->setCcTransId(NULL);
}
else
{
$transaction_completion = $this->_build($payment, self::TRANSACTION_COMPLETION);
$response = $this->_send($transaction_completion);
if($response->getResponseCode() > 0 && $response->getResponseCode() <= self::ERROR_CODE_LIMIT)
{
<!-- SUCCESSFUL CAPTURE -->
}
else if($response->getResponseCode() > self::ERROR_CODE_LIMIT && $response->getResponseCode() < self::ERROR_CODE_UPPER_LIMIT)
{
$payment->setStatus(self::STATUS_DECLINED);
$payment->setCcTransId(NULL);
}
else
{
$payment->setStatus(self::STATUS_DECLINED);
$payment->setCcTransId(NULL);
}
}
Observer.php
public function implementOrderStatus($event)
{
$order = $event->getEvent()->getOrder();
if ($this->_getPaymentMethod($order) == 'custompaymentmodule')
{
if($order->getPayment()->getCcTransId() == NULL)
{
$state = 'pending_payment';
$status = 'pending_payment';
$comment = 'Payment transaction failed due to incorrect AVS/CVD details.';
$isNotified = false;
$order->setState($state,$status,$comment,$isNotified)->save();
$order->setCanSendNewEmailFlag(false);
}
else
{
<!-- SUCCESSFUL INVOICE CODE -->
}
}
The only thing I'm left now with is to redirect the user to Shopping Cart page with an erro message at the top.
However since I need to do all this in Observer file, I'm not able to call $this->_redirect() method. Tried Mage::app->getResponse->setRedirect(Mage::getUrl('checkout/cart')) but dint work.
Any ideas on how to accomplish this last bit. }
I am using this to successfully redirect to cart page once the payment got failed.
Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::getUrl('checkout/onepage/index/'))->sendResponse();
